Grease injection device for bearings

Abstract

The invention relates to a grease injecting device for a bearing. The device comprises a bearing support disc module, a grease injecting module mounted above one side of the bearing support disc module, and a pushing and receiving module below one side of the bearing support disc module; the bearing support disc module includes a support disc mounted on a driving rotating shaft, and clamping rotating modules mounted on the support disc at intervals; the grease injecting module includes a bracket, a grease injecting head mounted on the bracket, and a grease injecting cylinder; an extruding block is mounted at the end part of a piston rod of the grease injecting cylinder, and is positioned in an inner cavity of the grease injecting head; a grease outlet hole and an outer stop grease ring and an inner stop grease ring respectively positioned on the outer side of the bearing outer ring and the inner side of the bearing inner ring are arranged at one end, towards the support disc, of the grease injecting head; a pushing plate is driven by a pushing cylinder on a support plate; a receiving plate is mounted in a clamping cavity of a rotary clamping disc; and a compression spring is mounted between the receiving plate and the side surface of the clamping cavity. The device has the characteristics of simple structure, high grease injecting efficiency and high reliability.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a grease injection device for bearings. Background technique [0002] After the bearing processing is completed, it is necessary to inject grease between the inner ring and the outer ring of the bearing. The existing grease injection device generally injects grease independently for a single bearing, the switching speed between bearings is slow, and the grease injection efficiency is low; moreover, after grease injection, some grease will remain on the inner side of the bearing inner ring and the outer side of the outer ring , affecting later packaging. The applicant applied for a patent titled "Disk-type Grease Injection Device for Bearing Processing", and the technical solution provided solved the above-mentioned problems. The improvement is that the clamping and removal of the bearings are manually operated, and the efficiency is low. . Contents of the invention...
